Use Mouse and WASD
Collect coins and purchase characters! Purchase and swap any character at any time. If you don't have enough, then you will be told that you can't buy that character.
Coins here are made to automatically spawn over time.
Click the Delete button to delete all progress. Reset purchases, money, and your character.
If you see "Not used in game", then that just means that its not needed to make a shop. Those bundles are used just so the character you playing as is automatically swap to what you purchase without restarting or going to another level. Usually, you wouldn't have a controlled character in the shop. The bundles would be good only if you do want a controlled character in your shop.
